Exponential synchronization of chaotic system and application in secure communication

This paper is concerned with the exponential synchronization of the chaotic system without linear term and its application in secure communication. The synchronization analysis is carried out by exponential stability theorem. Also secure communication is obtained by masking method and parameter modulation between transmitter and receiver. The error system exponentially is converged to zero. Numerical simulations are presented to illustrate the ability and effectiveness of proposed method.
